28、ber bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmen
29、tal and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISOAEC Direct
30、ives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elem
31、ents of this International Standard may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 6529 was prepared by Technical Committee ISO/TC 94, Personal safety - Protective clothing and equipment, Subcommittee S
32、C 13, Protective clothing. This second edition cancels and replaces the first edition (IS0 6529:1990), which has been technically revised. Annexes A to D of this International Standard are for information only. iv EN IS0 6529:2001 Introduction Workers involved in the production, use, transportation,
33、 and emergency response with liquid and gaseous chemicals can be exposed to numerous compounds capable of causing harm upon contact with the human body. The deleterious effects of these chemicals can range from acute trauma such as skin irritation and burn to chronic degenerative disease, such as ca
34、ncer. Since engineering controls may not eliminate all possible exposures, attention is often placed on reducing the potential for direct skin contact through the use of protective clothing that resists permeation, penetration and degradation. These test methods are normally used to evaluate the bar
35、rier effectiveness of materials used for protective clothing and specimens from finished items (see Note 1) of protective clothing against permeation of either liquid or gaseous chemicals. Options are provided for conducting this testing under both conditions of continuous or intermittent contact wi
36、th the chemicals. These test methods provide various options for reporting test results in terms of breakthrough time, permeation rate and cumulative permeation to allow a comparison of protective clothing material permeation resistance. These parameters are key measures of the effectiveness of a cl
37、othing material to act as a barrier to the test chemical. Such information is used in the comparison of clothing materials during the process of selecting clothing for protection from hazardous chemicals. Long breakthrough detection times and normalized breakthrough detection times as well as low pe
38、rmeation rates are characteristic of the best barriers. Resistance to penetration by liquid chemicals should be determined by using IS0 6530 while resistance to penetration by liquid chemicals under pressure should be determined by using IS0 13994. These International Standards are listed in the Bib
39、liography. It has been assumed in the drafting of this International Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people for whose guidance it has been prepared and that appropriate precautions will be taken to avoid injury to health and conta
40、mination of the environment. NOTE 1 Finished items of protective clothing include gloves, arm shields, aprons, suits, hoods, boots, etc. The phrase “specimens from finished items” encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.
41、 NOTE 2 using this test method cannot be used to infer safe exposure levels. At present, no quantitative information exists about acceptable levels of dermal contact. Therefore, the data obtained V EN IS0 6529:2001 Protective clothing - Protection against chemicals - Determination of resistance of p
42、rotective clothing materials to permeation by liquids and gases 1 Scope This International Standard describes laboratory test methods that enable a determination of the resistance of materials used in protective clothing to permeation by liquid or gaseous chemicals under the conditions of either con
43、tinuous or intermittent contact. Method A (see 8.3) is applicable to the testing of liquid chemicals, either volatile or soluble in water, expected to be in continuous contact with the protective clothing material. Method B (see 8.4) is applicable to the testing of gaseous chemicals expected to be i
44、n continuous contact with the protective clothing material. Method C (see 8.5) is applicable to the testing of liquid chemicals, either volatile or soluble in water, expected to be in intermittent contact with the protective clothing material. These test methods are only suitable for the testing of
45、air-impermeable protective clothing materials. They assess the permeation resistance of the protective clothing material under laboratory conditions in terms of breakthrough time, permeation rate, and cumulative permeation. These test methods also enable observations to be made of the effects of the
46、 test liquid on the protective clothing material under test. These test methods address only the performance of materials or certain material constructions (e.g. seams) used in protective clothing. These test methods do not address the design, overall construction and components, or interfaces of ga
47、rments or other factors which may affect the overall protection offered by the protective clothing. It is emphasized that these tests do not necessarily simulate conditions to which clothing materials are likely to be exposed in practice. The use of test data should therefore be restricted to broad
48、comparative assessment of such material according to their permeation-resistance characteristics. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
